| 1. An optical connector ferrule comprising:
a main body comprised substantially of a resin material,
wherein the main body comprises a first row of optical fiber holes and a second row of optical fiber holes,
wherein the two rows of optical fiber holes are positioned entering a front face of the main body,
wherein the first row of holes bends continuously towards the second row of holes as the first row penetrates a first distance
into the front face of the main body, and then bends continuously away from the second row as the first row penetrates an
additional second distance into the front face of the main body,
wherein the main body further comprises a stepped part with a first row of grooves communicating directly with the first row
of optical fiber holes, such that the first row of grooves may serve as guide grooves when inserting optical fibers from a
rear side of the main body,
wherein the main body further comprises a window for injecting adhesive, and
wherein the first row of grooves is at least partially visible through the window.
